How to get the version number of a SharePoint hosted App instance using JavaScript?

Hi,

Is there a way to find out the version of an App instance using SP JavaScript library? The App is SharePoint Hosted and has been deployed to the current site.

I have an aspx page which will be deployed to SharePoint online. On the page, I'd like to add some logic to check if a certain App instance exists at the site level, and display different message based on its version. I am able to use SP.Web.getAppInstancesByProductId() to get the instance but it has all information (title, url, Id, etc.) except the app version number. 

Thanks,

Matt.
